Have three recently purchased never opened Williams by Bachmann scale GG1's I'm looking to ugrade or mod. For those who've moded or upgraded these GG1s, what do you suggest? What gives the most bang for the buck? BTW, I'm not at all savy nor comfortable with opening up a loco so for any work done, I'd have to pay someone to do it. I'm especially fond of slow realistic running locos with sound and/.or cab talk chatter. So what options do I have? What are your suggestions and ideas? BTW, I can currently run conventional, DCS and TMCC systems but have no desire to upgrade to the Legacy system.
